Expertise

Full-stack, not front-end with extras. Every skill below links to the projects where it is actually used.

Frontend & interaction

Typed component systems, bilingual layouts and motion that explains what changed.

Backend & APIs

Servers that authenticate, authorize and validate everything they receive.

Data

Relational models with the security rules living next to the data.

AI systems

Agents that use tools, cite sources and ask before they act.

Quality & delivery

Tests that run in a real browser; hosting treated as its own concern.

Design

The design work that makes the engineering usable.

What I can build for you

Youssef Elalfy, Egypt

The interface and the system behind it, built by the same person.

I’m Youssef, a full-stack developer from Egypt. I came to code through interface design, moved into front-end engineering, and now build complete products: Laravel and Node APIs, Postgres and MySQL data models, and AI agents that call tools and cite their sources.

Working in Arabic and English shapes how I build. Right-to-left layouts are designed from the start, not mirrored at the end. So does a habit of honesty: every project on this site says what is finished and what is not.

Design makes the engineering usable. Engineering makes the design real.

How I work

  1. Understand

    Who uses it, what they are trying to finish, and what must never go wrong.

  2. Design

    Flows and states first — empty, loading, error, Arabic and English — then the visual layer.

  3. Engineer

    Typed boundaries, server-side rules and tests that run in a real browser.

  4. Refine

    Measure on real devices, cut what does not help, and label honestly what is unfinished.

Alongside the work: Google’s UX design foundations and research courses, and Microsoft Learn paths in Power Apps and AI tools.

Have something worth building?

A product, a role, or an idea that needs both an interface and a backend — tell me about it.
